NCR 53c700-66 MCA(EISA) doesn't want to work(2.4.x)

[Zdenek Styblik <stybla@turnovfree.net>]

Hello,

I have Intel Professional Workstation with LP468 motherboard which has
everything else except PCI. There is integrated SCSI controller NCR
53c700-66 50pin which is probably on MCA(or EISA bus). Problem is that
I can't make it work. I tried NCR 53c7xx, 8xx support(naturally), but
no way. I tried all other drivers, but no success. Googling around was
also unsuccessful. Everything points on that it should work, but it
does not.

# quote from Intel Professional Workstation documentation
1. NCR 53C700 SCSI I/O Processor (SIOP)
The on-board SCSI I/O processor is a NCR 53C700. This component has
internal FIFOs on the SCSI and host data
busses, 32-bit address and data busses, and an internal SCRIPTS
processor capable of fast DMA. A custom ASIC is
used to convert the 386-like bus interface of the NCR 53C700 to the
asynchronous strobed interface required by the
82359 DRAM Controller. The SIOP runs at 33 MHz, the maximum
theoretical data transfer rate is 66 MBytes/sec across
the Buffered Bus, and 8.25 MBytes/sec across the SCSI bus.

Do you have any ideas how to make this SCSI controller to work?

Thank you very much for your replies.
